I worked on a team that prototyped the “watch the game on your phone at the game” using WiFi. Nobody used it. That isn’t going to be the killer app either.
Livestream yourself watching the game / gig might be a thing though. I went to a Phoebe Bridgers gig in the summer and half the crowd seemed to be at it.
Not very good for the atmosphere though.
It working great and people actually wanting to use it are two different things. In my experience people go to sports events to experience the atmosphere and enjoy themselves while having a beer, not to look into every minute detail of what's happening.
Exactly... the most fanatical football nuts I know are the ones watching the game on TV with the different angles and the slow-motions and the replays... the people going to the game are very tribal, they love painting their faces and shouting [CITY NAME] and they do genuinely get very happy when [TEAM] wins but they aren't the ones talking about the 0-technique of the defensive lineman and so on.
Of course, but having been to an F1 race recently, the tracks are so irregularly shaped and long that it's usually impossible to see the whole track (or even more than some small section of track) from the stands. And even the big screens can be sparse.
It's been tried, and the results depend on your definition of "works great".
F1 used to have a deal with "Kangaroo TV" [1], where people at the race could rent a small portable TV. When I went to the Shanghai GP years back (it was the one where Hamilton beached his car coming into the pits), I rented one. With racetracks that are miles long so nobody can see all the action - and certainly not when sitting at Turn 1 in Shanghai - it's definitely a boon. I was able to see what was happening, even listen to the commentators. I was telling everybody around me what was really going on.
The thing is, it was fairly expensive. I don't remember the actual number, but something that you probably wouldn't just do on a whim.
And history tells us that it didn't work out. The "kangaroo.tv" domain name is apparently available for purchase now.
Too bad, because my experience is that, without this, going to an F1 race is inferior to watching on TV in most respects.
